Deyalsingh: 1 dead, 126 confirmed infections – Dengue alert

HEALTH MINISTER Terrence Deyalsingh has revealed that a resident of South Trinidad died recently from dengue fever – the country's first confirmed fatality from the virus since 2017. He also revealed that there have been 126 lab-confirmed cases of the disease, so far this year, in TT. As of April 30, 7.6 million cases of dengue have been reported globally with 3,000 deaths, according to the World Health Organization (WHO). Latin America and the Caribbean reported 9.3 million cases of dengue, so far this year, twice the number of cases reported in all of 2023, according to the Pan American Health Organization (PAHO). Deyalsingh made these revelations during an interview with i95 FM radio station on June 20. Due to privacy concerns, the minister did not disclose any further details on the fatality saying, "we have to protect the family's right to privacy, to let them mourn and come to terms with this." Speaking on TV6's Morning Edition talk show on Thursday, Chief Public Health Inspector Dr Mark Dookeran said the Ministry of Health is going to “get tougher” on delinquent households in the fight against the spread of dengue. “We have recognised that our education efforts are no longer enough and we are not getting the efforts we desire. “Through the office of the public health inspectorate, we are going to inspect homes and if we find things that should not be, we will be serving notices and laying charges in court for people found to be delinquent in cleaning around their homes. “Upon summary of conviction,” Dookeran said, “people can be charged up to $3,500 or six months imprisonment.” Dookeran said the ministry intends to “break the chain of transmission” by using ultra low volume (ULV) spraying once a case is detected. ULV spraying is done by a truck-mounted device which can apply insecticide to large outdoor spaces. This, he said, is usually done early in the morning as the aedes aegypti mosquito generally bites between dusk to dawn hours. “It doesn’t put our workers at risk when they go in to treat the homes and can take out the infected adult mosquitoes.” Once ULV spraying is completed, Dookeran said inspectors will visit the home of the affected resident to conduct perifocal work. “What this means is that we go into the home to identify and inspect both existing and potential breeding sites.” Dookeran said sites of interest include overgrown, bushy areas and stagnant water. “Three of the four stages of a mosquitoes’ life cycle are spent in water. At any given time, thousands of larvae can be in stagnant water. “It is much easier to kill that thousand larvae by knocking over a container as opposed to going around a community with a ULV machine to spray and using up all of our resources.” Dookeran added that the contents of the chemicals used to fumigate can have long-term effects on a person if spraying is done constantly. “While the doses we use are safe, if people are constantly inhaling these chemicals, it isn’t good for them.” [caption id="attachment_1091404" align="alignnone" width="775"] Health Minister Terrence Deyalsingh.

He urged the population to take precautions when spraying is being done. “Before it happens, the public is informed of the date and time we’ll be spraying and the precautions they can take.” He advised that while the chemicals are not sufficient to cause harm to humans, it can affect smaller animals like fishes and birds. CASES RISING Deyalsingh said there has been a global and regional increase in the number of dengue cases. He said this can be attributed to territorial expansion of the Aedes aegypti mosquito, its main vector, which has expanded its range to areas where it was not present before due to factors such as El Niño and climate change. “Because of changes like El Niño and La Niña, this means the mosquito population is reproducing faster.” He said on the global map, the regions being hit hardest by dengue are the Americas and this was due to global warming. Drawing on the example of the United States, Deyalsingh said there are now states being affected by dengue. “Those areas were temperate but with global warming, those states are now experiencing tropical climate conditions and are having dengue cases where there weren’t any before.” He said that in Trinidad, three districts are of concern: Victoria, St Patrick and Caroni. “Those are the counties that are contributing to the vast majority of the 126 dengue cases.” He said while TT’s infection rates are – for now – “relatively low,” the fatality was of concern and alerts the ministry to the fact that it must do all it can to prevent an outbreak. Deyalsingh said while he has engaged the Ministry of Local Government for assistance, he is calling on the population to be responsible and do its part to help. He urged the population to not see spraying as the “end-all-be-all.” “Spraying is part of a multi-pronged co-ordinated approach. While the ministry will continue its efforts on educating the public and co-ordinating fumigation of different areas, the real action is in source-reduction.” Deyalsingh said the ministry has not amped up its spraying efforts because new chemicals to eradicate mosquitoes have not been developed in 30 years. “If we spray more often, the mosquitoes develop a resistance and then we will have a bigger problem.” Deyalsingh said anywhere that has still, clear and stagnant water will become a breeding ground. “Clean your gutterings, flower pots, drains and vases inside your houses. All of these common sense approaches will help,” he urged. Deyalsingh admitted to being “horrified” when he discovered potential breeding sites in his own home. “I did an audit of my own home and found about three sites of concern. The major one was a bird bath which I moved out." DENGUE FACTS Dengue is a viral infection caused by the bite of an infected female aedes aegypti mosquito, primarily found in tropical and subtropical regions, according to the World Health Organization (WHO). It is sometimes referred to as "break-bone fever" because of the associated symptom of intense pains especially in the joints. Other symptoms include high fever, headache, nausea, and a rash. In severe cases, haemorrhagic fever takes place with consequent shock, internal bleeding, and death. There is no cure for dengue fever. In mild cases, treatment is focused on treating pain symptoms. Severe cases require hospitalisation while treatment of acute dengue is supportive and includes giving fluid either by mouth or intravenously. Most cases of dengue fever can be treated at home with pain medicine. Acetaminophen (paracetamol) is often used to control pain. Non-steroidal anti-inflammatory drugs like ibuprofen and aspirin should be avoided as they increase the risk of bleeding. According to online research site Wikipedia, there are two types of approved vaccines which are commercially available. Dengvaxia became available in 2016 but is only recommended to prevent re-infection in individuals who have been previously infected. The second vaccine, Qdenga, became available in 2022 and is suitable for adults, adolescents and children from four years of age. Apart from dengue fever, other mosquito-borne diseases include the Zika virus, West Nile virus, Chikungunya, malaria and yellow fever.   The post Deyalsingh: 1 dead, 126 confirmed infections – Dengue alert appeared first on Trinidad and Tobago Newsday.
